Chris Evans - who plays Captain America in the Marvel Cinematic Universe - has promised that the next 'Avengers' film will blow people's minds

The 34-year-old actor - who plays Captain America - is confident the films in the Marvel Cinematic Universe will continue to get bigger and better and insists the third film in the 'Avengers' series is going to be outstanding.

The Hollywood hunk is making his seventh appearance on screen as Captain America in a Marvel movie in 'Captain America: Civil War' and he admits he does feel pressure to stay in peak physical condition for his role as super soldier Steve Rodgers.

He said: "There's always pressure. It's seven or eight months of hitting the gym, constantly. It's not the worst thing in the world to make sure you're taking care of yourself.

"The Cap films are far more demanding, which you'll see in this one. There's more screen time and the amount of fights you're required to film are enormous. In 'Avengers', the plot is spread around. In this movie, even though we have a lot of other actors in it, the film is pretty much Steve's point of view, so there's more demand and responsibility when it comes to my scenes.

"I think it's gonna be very relatable. It's difficult to find resolve when you're fighting the people you love. It's a relatable story. It's not clear good vs bad, so hopefully it will prompt a lot of discussions."

In 'Civil War', Captain America and his allies feud against Iron Man (Robert Downey Jr.) over whether The Avengers superhero squad should be under government control.

The movie also stars Scarlett Johansson as Black Widow, Jeremy Renner as Hawkeye, Don Cheadle as War Machine, Paul Bettany as Vision and the first appearance in the Marvel Cinematic Universe of Spider-Man - portrayed by Tom Holland.
